The TR-100M digital temperature relay is a microprocessor device designed for measuring and monitoring the temperature regime of a dry transformer using four sensors
which is connected via two – or three-wire circuit, and then displays the temperatures on the display and issues alarm signals when any parameters go beyond the set limits.
The product can also be used to protect engines and generators.
The following types of temperature sensors can be used with the product:
- PT-100 platinum sensor with a nominal resistance of 100 ohms, at 0 ° C
- PT-1000 platinum sensor with a nominal resistance of 1000 ohms, at 0 ° C
- PTС-1000 (EKS111) sensor with a nominal resistance of 990 Ohms, at 25 ° С
- PTC (minika) cold sensor resistance 20-250 ohms
